Making Access Records Available to Lead American Government Openness Act or the MAR-A-LAGO Act This bill directs the President to establish and update, every 90 days, a publicly available database that contains records of: the name of each visitor at the White House, residence of the Vice-President, or any other location at which the President or Vice President regularly conducts official business (covered location); the name of each individual with whom the visitor met at the covered location; and the purpose of the visit. The President shall not include in the database any such record: (1) the posting of which would implicate personal privacy or law enforcement concerns or threaten national security, or (2) relating to a purely personal guest at a covered location. For a particularly sensitive meeting, the President shall: (1) include in the database the number of visitors at the covered location, and (2) post the applicable records in the database when their release is no longer sensitive.
